How to improve the electromagnetic compatibility of mobile phones by using electromagnetic absorbing materials for magnetic separators

In the context of increasingly complex functions and highly integrated internal components of modern smartphones, electromagnetic compatibility (EMC) has become a crucial issue. The numerous electronic components inside a mobile phone, such as antennas, chips, batteries, etc., generate electromagnetic radiation during operation and are also susceptible to external electromagnetic interference, which not only affects the performance of the phone but may also pose potential risks to user health. Developed by Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum brand mobile phone magnetic isolation sheet absorbing materialProvided an effective solution to improve the electromagnetic compatibility of mobile phones.

1、 The root cause of electromagnetic compatibility issues in mobile phones

1. Internal interference source
   • The RF circuit, baseband circuit, and display driver circuit in mobile phones are all potential sources of electromagnetic interference. For example, RF circuits generate high-frequency electromagnetic radiation when transmitting and receiving signals, which may interfere with the normal operation of other circuits. The digital signal processing in baseband circuits can also generate noise, affecting the audio, video, and other functions of mobile phones.
2. External interference sensitivity
   • Mobile phones are exposed to various external electromagnetic environments during use, such as Wi Fi signals, Bluetooth signals, and signals from nearby base stations. If the sensitive components such as the antenna of a mobile phone do not have sufficient anti-interference ability, they are easily affected by external signals, leading to problems such as call interruption and data transmission errors.

2、 Characteristics of Wave Absorbing Materials for Research Platinum Brand Mobile Phone Magnetic Plates

1. High magnetic permeability and absorption capability
   • Research Platinum brand mobile phone magnetic isolation sheet absorbing materialIt has a high magnetic permeability, which enables it to effectively guide magnetic field lines and change the distribution of the magnetic field. When there is magnetic field interference inside the phone, this material can concentrate and guide the magnetic field in a specific direction, reducing the impact of the magnetic field on other components. At the same time, its powerful absorbing ability can absorb and convert incoming electromagnetic waves into other forms of energy (such as heat), thereby reducing the impact of external electromagnetic interference on mobile phones.
2. Thinning and flexible design
   • This material adopts a thin design and can function without occupying too much internal space of the phone. In devices like mobile phones that require extremely high space, thin magnetic isolation absorbing materials can be conveniently installed near key positions such as antennas and chips. Moreover, its flexible nature enables it to adapt to the complex structural shapes inside mobile phones, closely adhere to various components, and improve electromagnetic compatibility.

3、 Specific application methods in mobile phones

1. Applications near the antenna
   • Installing research platinum brand magnetic isolation absorbing materials around mobile phone antennas can effectively reduce the mutual coupling phenomenon between antennas. For example, when there are multiple antennas in a mobile phone (such as Wi Fi antennas, Bluetooth antennas, cellular network antennas, etc.), these antennas may interfere with each other, affecting the efficiency of signal transmission and reception. Magnetic barrier absorbing materials can absorb stray magnetic fields around antennas, reduce coupling between antennas, improve the performance of each antenna, and enhance the communication capability of mobile phones.
2. Chip protection
   • Mobile phone chips are highly sensitive to electromagnetic interference. Placing the absorbing material of the platinum brand magnetic isolation sheet around the chip can provide a relatively stable electromagnetic environment for the chip. When other components inside the phone generate electromagnetic radiation, absorbing materials can absorb this radiation to prevent it from interfering with the normal operation of the chip. At the same time, absorbing materials can also play a role in shielding and absorbing external electromagnetic interference, protecting chips from interference and improving the overall stability of mobile phones.
3. Application in battery area
   • Mobile phone batteries also generate certain electromagnetic interference during charging and discharging processes. Use near the batteryResearch Platinum Brand Magnetic Barrier Absorbing MaterialIt can absorb the electromagnetic radiation generated by the battery and avoid the impact of this radiation on other components of the phone. In addition, it can also prevent external electromagnetic interference from interfering with the battery management circuit, ensuring safe charging and stable discharging of the battery, and extending its service life.

4、 The comprehensive effect of improving electromagnetic compatibility

1. Improve signal quality
   • By reducing the impact of internal and external electromagnetic interference, the electromagnetic absorbing material of the research platinum brand mobile phone magnetic isolation sheet can significantly improve the quality of mobile phone signals. During the call, it can reduce issues such as call interruptions and noise; In terms of data transmission, such as 4G/5G network data transmission, Wi Fi data transmission, etc., it can improve the speed and stability of data transmission, providing users with a better communication experience.
2. Enhance the stability of mobile phone performance
   • The various functions of mobile phones, such as camera function, sensor function, etc., all rely on a stable electromagnetic environment. The use of this magnetic barrier absorbing material can reduce the impact of electromagnetic interference on these functions, enabling mobile phones to operate stably in various complex electromagnetic environments. For example, when using a mobile phone camera to take photos or record videos, it can avoid problems such as screen flickering or data errors caused by electromagnetic interference.
